Specification of Letters Patent.

To @ZZ whom it may concern.-

Beit known that I, HARRY M. ABERNETHY, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented new and useful Improvements in Spectacle-Frames for Semaphore-Signals, of which the following is a specification.

This invention relates to semaphores; and one of the principal objects of the same is to provide a light, strong, durable, and efficient spectacle-frame for semaphore-signals.

Another object is to provide improved means for securing the glass in devices of this character, whereby the glazing may be accomplished without detaching the semaphoreiead or spectacle-frame from the signal-arm.

Still another object is to provide a strong sheet-steel spectacle-frame for semaphores which will be light and strong, which may be counterweighted to give the required poise to the arm and head, and which will be so pivoted that when actuated the full weight of the device will not fall upon the stop and have a tendency to break it off, as often happens in devices of this character as now in common use.

These and other objects are attained by means of the construction illustrated in the accompanying drawings, in which` Figure 1 is a plan view of a spectacle-frame or semaphore-head made in accordance with my invention. Fig. 2 is a transverse section on the line 1 1, Fig. 1. Fig. 3 is a plan view of the top plate. Fig. 4 is a side elevation of the same. Fig. 5 is a plan view of the ring for holding the glass disks in place. Fig. 6 is a section of the same.

Referring to the drawin s for a more particular description of the invention, the numeral 1 designates the spectacle-frame,which is formed of sheet-steel of the desired thickness and is provided with an edge flange 2, which extends entirely around the spectacleframe excepting at the point 3, which is designed for attachment to the semaphore-arm and is provided with perforations 4 for that purpose. A spectacle-frame for this purpose made of sheet-steel is very strong and durable and is comparatively light in weight. The edge flange 2 adds material strength to the structure. At the outer end of the device a counterwcight 5 is provided, and this may be obtained by casting or molding a quantity of metal at the point within the flange 2. If found desirable, perforations may be made in the base portion ay of the device in order that the molten metal 5 may be run through to attach the same firmly in place, or the counterweight may be suitably bolted or riveted to the spectacle-frame.

To secure the glass disks 6 in place, metal rings 7 are provided. These rings are provided with an overhanging flange 8 and a base-flange 9, the latter having three perforated lugs 10 for securing the ring in place by means of bolts 11. The glass disk 12 is held in place in the ring 7 by means of putty, cement, or rubber 13, as shown in Fig. 2. From this construction it will be seen that should one of the glasses be broken the ring 7 could be taken ofi` and quickly repaired without removal of the spectacle-frame. Upon one side of the spectacle-frame is a hub 14, provided With a flange 15, bolted in lace on the base ai. At the opposite side o the base a curved stop-plate 16 is secured, said plate being connected by bolts 17 to the base a and provided with opposite end stops 18.

From the foregoiinjr it will be obvious that a sheet-steel spectac e-frame provided with an edge flange is exceedingly strong and light and that the glass may be put in without removing the frame.

Having thus described my invention, what I desire to secure by Letters Patent and claim is- 1. A spectacle-frame for semaphore-signals, formed of sheet-steel of equal thickness throughout and provided with a strengthening-flange extending entirely around the peripheral edge thereof.

2. A spectacle-framefor signals pressed up from sheet-steel, provided with a peripheral flange, and a counterweight molded upon the outer end thereof.

3. A spectacle-frame for signals comprising a sheet-steel base provided with a peripheral flange and having a counterweighted outer end, and flanged rings for holding the glass disksin place, substantially as described.

4. A spectacle-frame for signals, pressed up from sheet steel having a peripheral flange, a weighted outer end, a cast-metal hub, and a curved cast-metal stop-plate, said hub and stop-plate being bolted to the base of IOO the spectacle-frame, substantially as del of, said stop-plate being curved and provided scribed. fr f l f d f Wthintegralstops,substantallyas described.

5. Aspect'aeleame or signes orme 0 sheet-steel, and provided with a, peripheral HARRY M' ABERNETHY Hange, and a east-metal stop-plate secured to In presence ofh one side of the case of the spectacle-frame, M. MILLARD,

and a hub secured to the opposite side there- H. D. ABERNETHY.
